Abstract: A Peltier element control device includes a drive circuit, a voltage detector, and a control circuit. The drive circuit supplies a current to the Peltier element. The voltage detector detects a voltage value of a voltage applied to the Peltier element. The control circuit causes the drive circuit to supply a current of a predetermined constant value to the Peltier element, and causes the drive circuit to reduce a magnitude of the current supplied to the Peltier element in a case where a value related to the voltage value detected when the current of the predetermined constant value is supplied to the Peltier element increases.
